METR's independent assessment finds ~2x AI R&D speedup at Anthropic, heavily redacted

METR published an independent assessment of Anthropic's October 2026 AI R&D acceleration, with top-line findings of roughly 2x speedup — but Anthropic redacted most of the evidence METR found most informative, citing risks of accelerating other AI developers. The author criticizes Anthropic for not matching words with action, notes METR said redacted evidence 'significantly informed' its 2x view (possibly ruling out alternatives like a one-off jump or RL free-lunch), and urges Congress to pace AI.
